Queries:
● Get a submitted paper’s details by the author’s Primary Key. The query should return the following data (columns): Paper.Id, Paper.Title, Paper.Abstract, Author.EmailAddress, Author.FirstName, Author.LastName
● Get all reviews for a paper by the paper’s Id, where the paper was recommended to be published. The query should return the following data (columns): All columns from the Review table.
● Get a count of all papers submitted.
● Create a new paper submission. Remember this includes creating new records in boththe Author and Paper tables.
● Try and Delete the first “Author” row in your Author table by the author’s id. Did you receive an error? If yes, print to the console the error you received. Also note in your message why the query failed. If it didn’t fail, print a message explaining why you were able to delete the row.
I use several sql String inside java file to make it.
/**

*/
sql1 = "SELECT * FROM AUTHOR,AUTHOR_SUBMITS_PAPER,PAPER "
+ "where author.EmailAddr=AUTHOR_SUBMITS_PAPER.EmailAddr_AUTHOR "

/**

sql7 = "delete from author where EmailAddr = 'James456@pace.edu'";
